Explain Angular services.

Services are a great way to share information among components/classes that don't know each other. Services can be injected into any component and it usually holds data/code providing data for one or more components.

To create a service using angular CLI, use the below command.

ng g service searchAPI

The above command generates 2 files, search-api.service.ts, and search-api.service.spec.ts, hold the code related to service and unit test specification for the service respectively.

search-api.service.ts file generated content follows:

import { Injectable } from '@angular/core';

  providedIn: 'root'
export class SearchAPIService {

  constructor() { }
